Before trying out our trick to clean acid stains on the floor, don't forget that DIY stores sell a whole range of special cleaners to remove all types of stains, including acid stains. In any case, it is important to act quickly and clean the stain as soon possible. Of course, you must take into account the characteristics and material of your flooring in order to choose the most appropriate product because acid stains can be quite fiddly to clean.


A home remedy that usually works for cleaning acid stains on floors is to use bicarbonate soda. The reason for using this product is that the bicarbonate neutralizes the damage caused by the acid to the flooring.

How to Clean Acid-Stained Floors - Step 2

To remove acid stains on the floor you must act immediately and sprinkle the bicarbonate sodium on the affected area, ensuring that you are protecting yourself with a sturdy pair of gloves, special work trousers and goggles. And don't forget to ventilate the room to avoid breathing in the highly toxic fumes. Let the product work for a moment or two and then remove the bicarbonate sodium using a cloth and some warm water.

Another trick that also works well for superficial stains is caustic soda. To clean acid stains on the floor using this ingredient, just do the same as for bicarbonate soda, as outlined above. That is to say, distribute the caustic soda on the affected area, leave it to work and then remove it. If necessary, you can reapply it to obtain better results.


But when acid stains on floors are very deep, the experts say it's best to cover it with a colour that matches as close as possible to the marked flooring. In this sense, a good solution would be to cover the stain with colored liquid wax until the acid is suitably camouflaged. For best results, you should apply it to the floor surface using a polisher that's specific for the type of flooring you have, be it marble or concrete.
